LANTERN.

Application filed August 19, 1909. Serial No. 513,694.

T 0 all whom it may concern:

Be it known that I, LEWIS A. ROBERTS, of Scranton, in the county ofLackawanna, State of Pennsylvania, have invented certain new and usefulImprovements in Lanterns; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, and tothe figures and letters of reference marked thereon.

This invention relates to improvements in lamps and lanterns and moreparticularly to that class of lanterns having an oil pot or base movableor removable with relation to the globe and upper part of the lantern,the object being to provide a simple and inexpensive device which willpermit the wick to be manipulated, either raised or lowered, and lightedfrom the exterior without the necessity of opening any part of thelantern.

Primarily the invention consists in mounting the igniter carrier andwick raising and lowering device on the same shaft, which is movable atwill, to throw either one or the other of said devices into operativeposition.

Further than this, the invention consists in certain novel details ofconstruction and combinations and arrangements of parts, all as will benow described and pointed out particularly in the appended claim.

In the accompanying drawingsFigure 1 is a perspective view of the baseof a lantern having my present invention applied thereto. Fig. 2 is aside elevation showing the wick manipulating devices in engagement infull lines, and the igniter carrier in position to bring the igniters incontact with the igniting surface, indotted lines. Fig. 3 is a detailtop plan view with the igniter carrier removed.

Like letters of reference in the several figures indicate the sameparts.

I have shown my invention as applied to an ordinary conductors lanternin which the base or oil pot and wick are removable through the bottomof the lantern frame, thus showing the adaptability of the invention toa type of lantern with which the greatest difliculty in applying devicesof this character would exist. However, it will be understood that I donot wish to limit myself to the application of the invention to anyparticular form of lantern or lamp.

The letter A indicates the oil pot which may be connected to the lanternframe in any preferred or usual manner, B the collar and burner screwinginto the top of the oil pot and having the usual wick raising or1owering shaft C. On the outer end of the shaft C is rigidly mounted agear or toothed wheel C and on the collar or burner between the shaftand wick tube is affixed the igniting surface for the matches origniters. As shown, this igniting surface is formed by the edge of asmall piece of metal D properly curved down at each end to facilitatethe movement of the igniters over the same and having a notch (Z just inadvance of the point at which the igniters come nearest the wick.

A vertical shaft E is journaled loosely in bearings on the side of theoil pot and passes down through the bottom where it is provided with ahandle or finger piece a to facilitate its movement. At the extreme upper end the shaft E carries the igniter holder F which consists of aplate having four or more points f bent into circular form as shown andadapted to work in proximity to the igniting surface when the shaft isin its lowest or retracted position.

Below the igniter carrier and wick raising shaft C and wheel C a gearwheel H is .mounted on the movable shaft E in position for its teeth toengage the teeth of wheel C when the shaft E is elevated or advanced,the gear wheels being entirely disengaged when the shaft is retracted.

For convenience the upper end of the shaft E is squared and the wheel Hand igniter carrier F are mounted on the squared portion, thuspreventing the independent move ment and by the application of a littlesolder they are held permanently in position and the shaft itself isalso held without further fastening means, as the movement in onedirection is limited by the igniter carrier and wheel H and in theopposite di rection by the handle or finger piece.

In operation, a series of igniter-s such as short friction matches aremounted in the igniter carrier imposition to strike and ride over theigniting surface, then, when it is desired to light the wick, the shaftis retracted or lowered and turned until one of the igniters strikingthe igniting surface rides up the same and is lighted as it crosses thenotch, being then in juxtaposition to the wick and will ignite the same.If this does not happen because of the remoteness of the igniter, theshaft is advanced and the igniter brought still nearer the wick thusabsolutely insuring a proper lighting of the same. When it is desired tomanipulate the wick or adjust the same, the shaft is advanced until thewheels H and C engage and the shaft is turned until the desiredadjustment is effected.

Ordinarily there is little danger of the unused igniters held by thecarrier becoming ignited from the wick at any adjustment of the shaft.However, in order to prevent any possibility of this happening, it issafe to only advance the shaft with one of the previously used igniterstoward the wick and as less than a quarter turn is necessary to turn thewick from the highest to the lowest point desired in ordinary use, noneof the unused igniters will be brought inward near the wick.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

In a lantern, the combination with a burner, a wick raising and loweringshaft journaled thereon and having a gear wheel at one end and anigniting surface in proximity to the burner, of an oil pot, alongitudinally movable shaft journaled in bearings on the oil pot, agear wheel mounted rigidly on the shaft at an intermediate point andadapted to mesh with the wheel on the wick raising shaft when elevatedand an igniter carrier mounted rigidly on the 1011- gitudinally movableshaft above the gear wheel and adapted to bring the igniters into linewith the igniting surface when the shaft is lowered and the gear wheelsare out of mesh.
